It takes a word processor 30 minutes to word process and spell check 4 pages. Find how long it takes her to word process and spell check 22 pages.
It will take the word processor 165 minutes to check 22 pages
How to determine the time to check the pages?The given parameters in the question are:
Speed = 30 minuter per 4 pages
Number of pages = 22 pages
The number of hours to check the pages can be calculated using the following equation
Time = Speed * Number of pages
Substitute the known values in the above equation So, we have the following equation
Time = 30/4 * 22
There is no unit to convert
So, we have
Time = 30/4 * 22

HElp using trigonometry how do I solve this?
By using trignometry we got the side p as 6.67
Use the cosine rule of trignometry to find side p
p² = r² + q² - 2rqcosP
To find the angle of p we will simply subtract angle R and angle Q from 180.
180 - 47.28 - 40 = 92.72
p² = 8² + 7² + 2(8)(7)cos(92.72)
p² = 107.685
p = √107.685
p = 10.38
Let's suppose that the shortest distance of R from PQ is .
look at the diagram I gave
since the line I made makes a right angled triangle, we can use SOH CAH TOA
for the angle 40, is opposite and 10.38 is hypotenuse
which means we will have to use SOH
sin40 = O/H
sin40 =x /10.38
0.6428 = x/10.38
0.6428 × 10.38 = x
x = 6.67
Hence, by using trignometry we got the side p as 6.67

Diana is packing a lunch that will include an orange. Diana has 3 navel oranges, 5 mandarin oranges, and 4 Valencia oranges. If Diana selects an orange at random, what is the probability that she selects a navel orange?
Give your answer as a simplified fraction.
Answer:
Step-by-step explanation:
1. Ok. Probability is something out of all. Add to get the bottom base of the probability.
3+4+5= 12
2. Probability is something out of something so 3 navel oranges can be represented out of 12 oranges.
3 out of 12
3. Make as fraction:
3 out of 12=
3/12=
1/4 or 25 Percent!
Answer: 1/4 or 25% ( If wanted as Percent)
Answer:
1/4
Step-by-step explanation:
Number of navel oranges = 3.
Number of mandarin oranges = 5.
Number of Valencia oranges = 4.
Let N be an event that Diana selects navel orange.
The total number of oranges Diana has:
n(T)=3+5+4=12n(T)=3+5+4=12
Number of navel Oranges is:
n(N)=3n(N)=3
The probability that Diana selects a navel orange is:
P(N)=n(N)n(T)=312=14P(N)=n(N)n(T)=312=14
Hence, the probability that Diana selects a navel orange is 1414.

y = 10
substitute y = 10 into (1) and solve for x

tire could roll 200 yards in 27.28 revolutions , what is the radius of the tire?
The radius of the tire is 1.17 yards.
According to the question,
We have the following information:
A tire could roll 200 yards in 27.28 revolutions.
We know that the tire is in the shape of a circle.
We also that the following formula is used to find the circumference of the circle:
2πr where r is the radius of the circle
Now, we have the following expression:
2πr*27.28 = 200
54.56πr = 200
r = 200/54.56π
r = 200/54.56*3.14
r = 200/171.32
r = 1.17 yards
(The unit of the radius will remain same as that of the distance given.)
Hence, the radius of the tire is 1.17 yards.

A basic cellular package costs $40 /month for 60 minutes of calling with an additional charge of $0.20 /minute beyond that time. The cost function C(x) for using x minutes would be
If you used 60 minutes or less, i.e. if if x≤60 , then C(x)=40 (the base charge).
If you used more than 60 minutes, i.e. (x−60) minutes more than the plan came with, you would pay an additional $0.20 for each of those (x−60) minutes. Your total bill would be C(x)=40+0.20(x−60) .
If you want to keep your bill at $50 or lower for the month, what is the maximum number of calling minutes you can use?
Answer:
78
exclamation is that if 50 is lower than 60 which it is meaning that 78 is the correct answer if you multiply 18 + 34 that is not the right answer but there should be a right answer under this question you shouldn't trust me because I do not give a what the answer is I do not suggest you write down this answer but you do your top G
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.
To keep your bill at $50 or lower for the month, you need to set up an inequality using the cost function C(x):
C(x) = 40 + 0.20(x - 60)
Since you want to keep the cost at or below $50, the inequality is:
C(x) ≤ 50
Now, substitute the expression for C(x) into the inequality:
40 + 0.20(x - 60) ≤ 50
40 + 0.20x - 12 ≤ 50
0.20x + 28 ≤ 50
Now, isolate the term with "x" on one side by subtracting 28 from both sides:
0.20x ≤ 50 - 28
0.20x ≤ 22
Finally, divide both sides by 0.20 to solve for "x":
x ≤ 22 / 0.20
x ≤ 110
The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.
